The cost estimating process considers whether the expected savings can offset the cost of the additional design work. Cost estimates are generally expressed in units of (2 )to facilitate comparisons both within and across projects. The(3 )describes the business need, justification, requirements, and current boundaries for the project. It provides important information about project requirements that is considered during cost estimating.
